When experimental drilling on the pacific sea-bed breaks through the earth's thin mantle, vast quantities of nitrogen, trapped for untold millions of years, are released into the atmosphere. As a result, the oxygen in the air becomes dangerously diluted. Whole areas of America are thrown into chaos as the inhabitants literally fight for breath. Two men and two girls put to sea in a yacht in a desperate effort to escape the terror, but terror, in a different and no less deadly form, pursues them relentlessly.

Charles Forbin has dedicated the last 10 years of his life to the construction of his own supercomputer, Colossus, rejecting romantic and social endeavours in order to create the United States' very first Artificially Intelligent defence system. Colossus is a supercomputer capable of taking in and analysing data rapidly, allowing it to make real-time decisions about the nation's defence. But Colossus soon exceeds even Forbin's calculated expectations, learning to think independently of the Colossus Programming Office, processing data over 100 times faster than Forbin and his team had originally anticipated. The President hands off full control of the nation's missiles and other defence protocols to Colossus and makes the announcement to the world that he has ensured peace. However, the USSR quickly announces that it too has a supercomputer, Guardian, with capabilities similar to that of Colossus. Forbin is concerned when Colossus asks - asks - to communicate with Guardian. The computer he built shouldn't be able to ask at al

Modern man's most persistent and powerful dream is about to come true. He is ready to travel through time. And who better to take the leap than Mark Elverson, a man with an inoperable heart condition? The far future can only be an improvement for him ... or can it?

Alien horror becomes a living nightmare as the Xenos, meaning "strangers", inflict mayhem on earth. International distress alerts are sent out when planes first seem to disappear, disturbing concepts of space and time and leaving a trail of death and disillusionment. This bizarre series of "cosmic skyjackings" is shrouded in secrecy by a baffled and frightened military. Intense surveillance fails to reveal the cause of a seemingly hostile yet invisible enemy. Aircraft continue to disappear, plucked out of the sky without warning, only to reappear months later, thousands of miles off course. National and global security is under threat and the ICARUS committee is formed to investigate. Military officials, the government and the FBI work alongside physician Mark Freedman and Soviet scientists to uncover the supernatural mystery that lies behind these unexplainable events. Earth has been found by a horde of creatures that not even the wildest imagination could invent - sinister parasitic creatures that took to their human hosts with deadly speed and bloodthirsty precision. The terror that unfolds has terrifying consequences for all involved, and the invasion reveals something much more frightening and final than ever suspected.

The hugely powerful and pervasive presence of the Colossus supercomputer mechanically runs Earth and its myriad operations. Managed by its creator, Dr. Charles Forbin, it is incapable of lies and void of human emotion. It is not a robot and not human. As part of its brief to enhance the human race, it runs eerie emotion research centres, authorizing acts of savagery to measure resistance and feeling. Art and abstract creation are banned, and surveillance is constant. No one is free. The power of Colossus is spiralling out of control. The Sect worship it as a God, enforcing its word at every opportunity and seeking out traitors. The Fellowship secretly oppose it as a force of evil, and they risk their lives in a concentrated effort to destroy it and escape its domination. Meanwhile, as Forbin becomes increasingly disillusioned with what he has unleashed on the world, his wife, Cleo, becomes distant, with disastrous consequences.

The Taking of AT1: Before AT1 had ground down the slipway unchristened - rightly, said seamen, for it would be a ship with no soul - it had been dubbed 'Zombie'. That sinister name would stick and prove its accuracy. AT1 was a robot-ship, a ship with no crew, only a tiny security force of three men & a woman. 'Invulnerable,' said its inventors, 'foolproof'. But it was neither - not if one of the four security guards was an insane, ruthless killer. And if the greatest, most powerful self-contained nuclear reactor in the world fell into the hands of such a person, the whole world was in peril!

Breeding machines and fertility camps. When a foreign power puts a sterility drug in Britain's reservoirs, the result is all too predictable. The birth-rate plummets and the country's future looks bleak. There is only one way to save the nation; all women with a natural immunity to the drug must be placed in special camps where they can be bred from like prize cattle. They must be given special hormone treatment and artificial insemination so that they can produce triplets, quads, quins time after time until they die of exhaustion. They must become Nation Mums, the sole hope of a desperate people. They must be pampered and disciplined to accept their role. Even if one of them happens to be the wife of the Minister in charge of the whole terrifying affair...

The 22nd Century. Dr. Charles Forbin is Earth's most powerful man. As mediator between Colossus, the Super Computer, and the rest of humanity, Forbin holds the key to Earth's fate. When Colossus, an awe-inspiring technological creation, suddenly became self-aware and took upon itself the task of righting humanity's wrongs with no regard for humans themselves, Forbin intervened. He took the decision to turn off his great machine - but could not do it alone. Forbin called upon invaders from Mars. The Martians did their fastidious work, shutting down Colossus. The Earth descended into chaos. Rival factions sparred for supremacy, with only Forbin to control the populace and maintain order. But now, the Martians have returned. And they want compensation. Forbin is asked to design a super Collector in order to solidify the Earth's supply of oxygen - or, a large proportion of it - to be handed over to the Martians. But to do so would condemn the lives of hundreds of millions of Earth's inhabitants. There is only one entity on Earth with the power to stop the Martians...Colossus must return.
